Question

the area of a square is equal to the area of a circle. What is the ratio between the side of the square and the radius of the circle

Answer 1

as we know that

are of square = side^2

area of circle =pie × r^2

area of square =area of circle

so

s^2=22/7×r^2

s^2/r^2=22/7

s/r=root22/7

Answer 2

Area of square = a^2
Area of circle = pie r^2
According to question
a^2 =pie r^2
a^2 /r^2 =pie
a/r=(pie) ^1/2
